I recently purchased one of the diesel variants available for the Maruti Suzuki Ciaz. I picked the Ciaz due to all the safety features it was packing, as driving in the city can be quite troublesome. I am happy with the efficiency, both in performance and in mileage, the car is giving me, but I have noticed that the diesel engine seems to under-perform if I am comparing it with the petrol variants some of my friends have. I haven’t required any maintenance as of yet, and the car is easy to drive under city conditions on a regular basis.
